Task & Function of Mercedes Torque Converter

The torque converter has 2 tasks. It serves as a hydraulic start-up clutch, and as an additional transmission, which is upstream of the gearbox. Since the power transmission is hydraulic, the start-up is very soft and therefore also material-friendly.

The pump wheel has straight shovels. The converter housing is connected to the pump wheel on the crankshaft. This means that each rotational movement of the motor is transferred directly to the pump wheel. The turbine wheel has curved blades. The turbine wheel is firmly connected to the planetary wheelset by the gear input shaft. This transmits each movement of the turbine wheel directly to the planetary wheelset. The blades of the turbine wheel are bent in such a way that a certain deflection of the oil is achieved. The guide wheel is mounted on the pump tube with a freewheel. The blades of the Leitrade are shaped in such a way that the oil jet coming from the turbine wheel hits the back of the pump wheel with the remaining force.

Start-up phase, the individual wheel blades are also shaped so that the oil flow from the turbine wheel is deflected at speed difference between pumps and turbine wheel on the guide wheel, and then changes direction at the guide wheel wings and at such an angle into the pump wheel that it hits the back of the blades, supporting the work of the pump wheel and increasing its performance. This results in the torque gain of the converter, which fluctuates between approx. 2:1 and 1:1.

In driving mode, when the turbine wheel speed has reached 90 of the pump speed, the guide wheel is shoveled with oil from the turbine wheel at a flat angle, forcing it to turn along in the rotational sense of the turbine and pump wheel. From this speed threshold, the torque is no longer increased, but the converter now acts as a pure flow clutch. The hydraulic power transmission causes slip in the converter. This means that the speed of the motor-side pump wheel is higher than that of the gear-side turbine wheel. Converter slip increases fuel consumption, and thus pollutant emissions. A converter bridging coupling (WÜK) provides a mechanically force-locking connection to remove the slip under certain load conditions.

ATT24 offers its customers new torque converters. Thanks to our extensive stock of over 1000 torque converters, we are able to deliver most torque converters on immediate request. However, if your torque converter is not included, we also offer repairs on defective converters.
